PRESENTATION OF EDF GROUP Description of the Group's activities

As part of the transparency sought by RTE, the éCO 2 mix application, launched in 2011 and publishing data relating to the consumption and generation of electricity over the whole of France, is experiencing increasing success, with 10 million consultations per annum and direct access to 15 million data-points, which bears witness to the general public’s interest in energy issues. This application contributes to better informing all citizens and to raising their awareness of the challenges of the new energy policies. Energy balance 1.4.4.1.2.1 2017 Summary In 2017, gross consumption stood at 482TWh, i.e. -0.3% compared to the previous year. Temperatures in 2017 were higher than those recorded last year (+0.6°C), which accounts for part of this decrease. During the cold wave on 20 January, electricity consumption peaked at 7 p.m., with power output of 94GW. This represents the third highest peak ever recorded in France. Although the 2012

thermal regulations will moderate future temperature sensitivity, the sensitivity of consumption to temperature remains around 2,400MW/C in winter. Excluding the energy sector, adjusted consumption reached 475TWh in 2017. For the seventh consecutive year, annual electricity consumption remained stable in France. Consumption of major industrial customers directly connected to the public transmission network amounted to 68.2TWh in 2017. This represents an increase of more than 3.5% compared to 2016. An increase in the consumption patterns of major industrial customers has been noted since May 2016, reflecting the sector's renewed business activity. Equivalent outage time is an indicator used to measure the quality of supply of electricity by RTE. In 2017, equivalent outage time was 1mn 27s excluding exceptional events. This result, coming in below the 2mn 48s threshold set by regulatory incentives, confirms the measures put in place by RTE to improve the quality of supply of electricity to its customers.

Renewable energies continue to grow in order to foster the energy transition The installed wind turbine capacity amounted to 13,559MW at 31 December 2017. Wind power generation saw a sharp increase of 14.8% compared to 2016. Driven by the increase in installed capacity, wind power generation benefited from favourable weather conditions at the end of the summer and especially in December. A new maximum wind turbine production rate was recorded on 30 December at 1:30 p.m. with power output of 11,075MW. The associated load factor reached 81.8%. With 887MW of new solar capacity connected in mainland France, installed solar capacity reached 7,660MW. Solar generation increased 9.2% compared to 2016, in line with the increase in installed net capacity. Benefiting from the hours of sunshine during the spring months, monthly electricity generated by the solar power segment exceeded 1TWh for more than five consecutive months, setting a new record. The French balance of trade showed lower exports at the end of the year The French balance of trade amounted to 38TWh in 2017. This is an even lower level than in 2016 which was already remarkably low. The results for January and November even showed imports, with -0.95 and -0.83TWh respectively. Such monthly commercial balances had never previously been reached, even in February 2012 (-0.72TWh).

The position of cross-border contractual exchanges in 2017 is as follows: France's trade surplus with Spain was up sharply, reaching 12.5TWh, a record ■ level; as in the previous year, France was a net importer from the Central West Europe ■ region, with a trade deficit of 10.9TWh: this is explained by the reduced availability of the French nuclear fleet and the abundance of wind power generation in Germany; France continues to have a trade surplus with Switzerland (10.3TWh); ■ the trade surplus was 18.2TWh with Italy and 7.9TWh with Great Britain. New ■ interconnection projects are in particular being planned on these two borders. Maintenance of the transmission 1.4.4.1.2.2 infrastructure RTE manages the assets of the transmission network through daily maintenance, emergency repairs and replacement of structures that are at the end of their useful life or are damaged. Implementation of a mechanical safety programme in response to extreme weather events to make the electricity grid more robust and more resilient was completed at the end of 2017, in accordance with the commitments made with the relevant Ministry following the storms of 1999. This programme cost close to €2.8 billion. The low impact of these latest storms proves the programme's effectiveness, especially regarding the role played by anti-cascading safety towers. At the end of 2017, 100% of target connections were automatically secured. Starting in 2018, RTE will ensure the continued existence of this secure network.
